Remove casserole from oven. Place biscuits on top of chicken mixture and return to oven. Bake about 10 minutes or until biscuits have risen and are light gold. Reduce oven temperature to 350°F. Continue baking 10 to 15 minutes or until biscuits test for doneness and casserole is heated through. During the last five minutes of baking, sprinkle paprika over biscuits.
